摘要

Cogeneration power plants combine the benefits of steam and gas turbines driving only one generator within a single shaft. The shaft of the steam turbine is coupled to the main shaft line including the generator and the gas turbine through a SSS-clutch.This paper introduces a concept for the identification of coupling angles with low amplitudes of vibration at the bearings. The method is based on the theory of rotor dynamics and needs only few measurements of the bearing vibrations near the SSS-clutch and the rotation angle between the two shafts. The bearing vibrations are displayed as orbits of the shafts centre. Using the complex calculus, these elliptical orbits can be separated into a circular part revolving in the rotating direction and another circular part revolving in the opposite direction. Depending on the phase shift between the unidirectional parts of both shafts, angles with low bearing vibrations can be identified. The identification concept of advantageous angles is applied to measurements of operating units. The determined coupling angles are in good accordance with the measurements as shown in the paper.
